IMPROVED WASHING-'MACHINEl Specification forming part of Letters PatentN0. 39,3413, dated July Q8, 1563.

INashing- Machine;` and 1" do hereby declare that'the following isafull, clear, and exact V'description thereof, reference being hadto theaccompanying dra-Win gs, making a part of this specilication, in which nFigure 1 is a vertical longitudinal section taken through the` center ofmy improved maf chine. Fig. 2 is -a top view of the machine.' Fig. 3 isa'plan view ot' the vibrating rubbing. rollers. Fig.'4 is a faceY viewof the washboard; and Figs. 5 and 6 show, respectively, atransverse andalougitudinal section through Fig. 5.

Similar letters of reference indicate corresponding part-s inthe severalfigures.

This invention relates to certain new and useful improvements on themachine secured to me by Let-ters Patent bearing date May 4, 1858.

The object of my present invention is to more effectually prevent thearticles beiug'washed from working out at the ends of the rubbingrollersand causing the machine to work hard and imperfectly, and at the sametime to pre- .veut any undue straining of the articles..

It also-has for its object ei'ecting an economy of soap by subjectingthe articles to much stronger soapsud's while they are being rubbed thanis contained in the body of the wash-tub, all as will be hereinafterdescribed and represented.

To enable others skilled in the art to make and use. my invention, Iwill proceed to describe its construction and operation.

In the accompanying drawings, A represents the wash-box, which isconstructed with verti-r cal longitudinal sides and inclined ends, and aledge, a, surrounding the upper edge at one end of the box, as shown 'inFig. 2. This box A is mounted on legs B B, and has two uprightstandards, C C, affixed to the sides, which project yup some distanceabove the box, and receive in their ends groovcd bearing-boxes b b,which are mounted on springs c c, and receive and support thetranslverserock-shaft D, which supports the rubbing-rollers d d d. The ends of therock-shaft D project out from the outside ot' each block baud receivethe ends of connecting-rods e c,

which proceed downward and are attached to the ends of a transverse rod,f, whichhas'connected to it a treadle, E.' This treadle 1s used fordepressin g jthe rollers d d d, and the springs c'c are used for'elevating the .rubbing-rollers d d d.. The lrollers d havetheir'end'bearings in the segmental. side pieces, g g, which are,connected together by transverse bars g"g, l and the 'whole areconnected to parallel `arms h h,`which are 'suspended from therock-shaft D. In one end of the box Athe"cncave or wash-board isarranged, the surface ot'which is concentric with the center ofvibration of of the rubbing-.rollers when these rubbers are at theirhighest point.- (Shown in-Fig. l.) This wash-board .is made up of anumber of slats which have spirally-ribbed surfaces, the ribs of whichrun in opposite directions on each alternate slat, so that a number ot'such slats, t' i, arranged side by side, present the appearance ofzigzag-ribs running-from one side'of the box to the other, as shown invFigs. 2 and' 4. These spirally-ribbed slats t' incline downward from theupper toward the lower end of the inclined'end of box A, and they arenailed to transverse ledges lc 7c 7c. (Shown in Fig. l.) These rubbingsurfaces or slats are furnished with a bottom board, G, which formsaspace, m, beneath them for containing strong soapsuds, vand the ledgesk 7c keep a sufficient quan'- tity of soapsuds under the slats for allpractical purposes. The serrated or scalloped edges of the slats t' i donot :tit so closely together as to prevent the soapsuds beneath themfrom mixing with the water which is drawn up from the main body-ofthe'tub A with the clothes as they are brought 'over these slats to berubbed; but should' these spaces not be found sufficient, the slatsthemselves may be perforated, the perforations be-r ing made between theribs, -as shown in the drawings, Figs. 2 and 4.' The rubber is composedof a number of rollers, d d, arranged in a curve 'concentric withl theaxis ot' the rockshaft Dl (Shown in Fig. l.) These rollers are spirallygrooved, the grooves running 'from oneendof one roller to abouttwo-thirds the length of this roller'in'one direction,'and for the otherthird in the opposite direction', Thus, at the ends of these" rollersthe groove'srun in opposite directions, the object ot' which is to causethe rollers to move the clothes, which are subjected to their rubbingaction, toward having a right and left spiral groove formed.

in its surface, the tendency is to move the clothes back and iorthlaterally on the Wash- 'board7 and thus to subject every portion thereofto the rubbing and squeezingaction of the two spirally-grooved surfacesof the rubber and wash-board.

In using the machinewater is put into the main body of the tub, andstrong soap and water, soft soap, 'or washing co1npound7of anydescription, and the clothes are drawn from the rinsing Water in the tubover the concave wash-board where the soapsuds. contained in the spaceon will mix with the water in the clothes as they are rubbed andsqueezed by the rubbing-*rollers d d d, the'pressure of these rollersbeing increased or diminished on the clothes by pressing with greater orless force upon the treadle E. The strong soapsuds can in this way bebrought to actdirectly up-4 on the clothes in only such quantities asmay be required, and being kept in a sepaiate receptacle there will be agreat deal of soap saved which would otherwise be mixed With the body ofWater in the tub A.

What I claim as'my invention is 1. The wash board lcomposed ofalternately rightand left or zigzag open surfaces, substantially asdescribed.

2. A wash-board constructed with a soapf suds receptacle, m, arrangedbeneath the openslatted surface i i, substantially as and for thepurposes described. l

3. Combining with the zigzag-ribbed and waved Wash-board thespirally-ribbed rollers7 the ribs of Whichrun in opposite directions oneach roller, substantially as and for the purposes herein described.

Witness myhand in the matter of my application for a patent for animproved Washing-machine this 11th day of June, A.D. 1863'.
